Truthear PURE Triple Driver IEM

High-Performance Hybrid IEM with Punchy Bass, Clear Mids & Sparkling Highs

Discover the Truthear PURE, a premium in-ear monitor engineered for audiophiles seeking detailed, accurate, and musical sound. Featuring a hybrid 1DD + 3BA driver setup, PURE is designed to deliver superior resolution, a smooth three-frequency balance, and impressive technical performance.

Key Features:

✅ Hybrid 1DD + 3BA Driver Configuration

PURE utilizes a 10mm dynamic driver with a silicone suspension + liquid crystal polymer (LCP) dome diaphragm, combined with three high-precision balanced armature drivers. This configuration ensures deep, tight bass, a solid midrange, and extended, detailed treble response.

✅ Precision-Tuned Sound Signature

Built on the design principles of the acclaimed HEXA, PURE offers a more dynamic and refined sound. The tuning aligns closely with the HRTF target curve measured by the BK5128 HATS, delivering accurate frequency crossover and natural tonal balance.

✅ DLP 3D Printed Acoustic Chamber

Crafted using DLP 3D printing technology from HeyGears, the PURE’s internal cavity is engineered for perfect acoustic performance and consistent quality. The resin shell is both lightweight and skin-friendly, ensuring long-lasting comfort.

✅ Superior Frequency Crossover Design

Each driver is paired with a dedicated nozzle and optimized RC crossover network, resulting in clean transitions between frequencies, enhanced detail retrieval, and phase-coherent imaging.

✅ Silver-Plated Coaxial OFC Cable

Included is a high-purity oxygen-free copper cable, silver-plated for better conductivity and tonal transparency. Terminated with a 0.78mm 2-pin connector, the PURE is fully cable-swappable for easy upgrades or personalization.
